Bah, the KSC75's clips are just not good for the KSC35. I mean it sounds good, but the point where the clips connect to the KSC35 allow too much freedom and distance for the drivers and pulls it away from the ear, losing bass. Ironically, the KSC35 clips make the KSC75 sound better than the stock clips. Still, the KSC75 sounds better than the KSC35 when compairing them both with the KSC75 rubber clips, and the KSC35 sounds better than the KSC75 when using the KSC35 clips. All in all, best to keep the KSC35 clips on both for sound quality, and using the KSC75 with it's stock clips for comfort. What's interesting is that the KSC75 clips are actually harder to put on my ears than the KSC35.
So what I'm gonna do is use the KSC75 for work, when and only when the KSC35 starts to bother my ears, which is usually halfway through the shift, so they will definitely be getting their use. Put the KSC75 on, and immediately fell in love with them again.
I wanna get some thin electrical tape and see if I can wrap it around the KSC35's clips so the hard edge doesn't dig into my ears.
Wanna know what's funny? My HE400 literally came in 2 minutes before the KSC75, and yet I haven't bothered with them yet. Lol. I did open them, and was happy to see the spare velour pads were packed in the HE400 box (though the pleather was on the HE400 itself.)
edit: Holy crap, I put on the HE400 (hooked up just to the E17 on Gain 0, and that SQ boost is ridonkulous. Holy crap. Lol. Insta-love.
